. Application filed December 12, 1882. (Model.)

T0 all whom it may concern:

Be it known that I, MrLns EDWARD PETER- soN, a citizen of the UnitedStates, residing at Chilton, in the county of Calumet and State ofVisconsin, have invented new and useful Improvements in Shutter-Vorkers,of which the following is a specification.

My invention relates to improvements in shutter-workers; and it consistsin means or apparatus for effecting the opening and closing of the sainewithout necessitatingthe opening or raising of the sash.

The nature of my invention will be fully explained by reference to thefollowing` specification and the drawings annexed, which form part ofthe same.

Referring to the drawings, Figure 1 is a partial internal front view.Fig. 2 is a horizontal section of so much of a window-casing as willillustrate my invention. Fig. 3 is a detail view. i

In each of the views similar letters of reference are employed toindicate corresponding parts wherever they occur. Y

A represents a portion of a window-frame, B a part of the sill thereof,and C a. portion of the sash. D is a quadrantal rack, formed withnotches d and teeth d. Therack D has its horizontal side attachedtoabed-plate, D', which is screwed or otherwise affixed to the sill B,and its vertical side is attached to or rests against the vertical sideof the windowframe B. Near the angles of the quadrant is a pivot, e,upon which is mounted a lever, E, which is operated as hereinafterexplained.

To the lever E, at e", is pivoted a curved, slotted, or toothed bar, G,the slots or teeth g of which engage with the teeth ZL of a toothedwheel, H, mounted on a shaft, H, revolving in bearings in thewindow-frame. The slotted or toothed bar G is kept in contact with theteeth of the wheel H by means of a follower, I, controlled by a spiralor other suitable spring, IQ supported in .position by a bearing orstud, l2. Upon the outer end of the shaft H is a bevel-wheel, H2,arranged outside of the window-frame, and engaging with lacorrespondingly-formed bevel-wheel, H3, formed on or affixed to one ofthe hingepieces HL (by preference the lower) of the blind-frame J. I Thepivoted lever E, at its forward end, is provided with a socket, e2,adapted to receive the endf of a bent lever,

F, which is provided with a handle, F, on

the side of which is pivoted a lever, K, to the short arm k of which ispivoted one end of a rod, k2, the opposite end of which is formed into ahook, f4. rIhe rod 7a2 worksin keepers, between which is a spiral springsurrounding said rod, and having one end attached thereto.

In the lever E in line with the socket e2, and separated therefrom by apartition, is'another socket, in which works a block or plunger, k3,between which and the partition is a spiral spring. This block orplunger is arranged to engage in the notches (Z between the. teeth d ofthe quadrantal rack D and hold the levers E and F in any desiredposition. The levers E and F are connected together, when desired, bymeans of a latch, L, pivoted to a pin extending outward from the plungerk3 through a slot in the lever, E, asv shown in Fig. 3. The forward end,Z, of said latch L is formed with a projection or detent, Z', adapted toengage with lthe hook f4, formed in the end of the rod k2, while therear end, Z2, is extended so as to form a lever, by means of which theprojection or detent Z may be disengaged, and the hook f 4 and thelevers E and F separated, when desired. The latch L is provided with acoiled or other suitable spring, Z4, for the purpose of keeping theprojection or detent in position when the levers E andF are latchedtogether. The lever E, at its forward end, is provided with anextension, Ef, adapted to embrace the quadrantal rack D, so as toprevent lateral motion thereof and consequent strain on the axis orpivot e.

The levers E and F, if desired, may be rigidly connected together; butin such case each device must be provided with a lever, F, and itsoperating parts, whereas by forming the lever F detachable one leverwill serve for a series of blinds, either in the same or adja` cent roomor chambers.

By my improvements it will be readily seen that by simply raising orlowering the lever E by the lever F, so as to operate the bevelwheels H2H3, the blind J will be opened or closed without necessitating4 theraising or opening ofthe sash or window. By grasping the handle F anddepressing the long arm 7.:

IOC

of the lever K, the rod k2 is drawn in such-a manner that, by itsconnection with the'block or plunger k3 through the latch L, said blockor plunger is disengaged from the notches, so as to pass over the teethwhile the lever is in motion, and when the lever K is released thespring forces the rod back, and the plungeragain engages with the notch.

Although my invention is particularly designed and intended for blindsor shutters haviug movable slats, it will be seen that I can withfacility apply the opening and closing mechanism to solid or paneledshutters supported on hinges on the exterior of abuilding or structure.

Having thus described my invention, what I claim, and desire to secureby Let-ters Patent, is-

l. The combination, with a Window-casing and external hinged blind orshutter, of a pivotcd lever, E, quandrantal rack D, bar G,spring-follower I, Wheel H, shaft H', bevelgear H2, bevel-gear H3, andhinge-piece H, substantially as shown and described.

2. The combination, with a window-casing and an external hinged blind orshutter, of a pivoted lever, E, quadrantal rack D, bar G, wheel H, and aremovable lever F, provided with aholding-catch, 7c3, and aretaining-catch, la kif* L Z', substantially as shown and described. l

3. The combination, with the operating mechanism of a device for openingand closing window blinds or shutters, of the notched or toothedquadrantal rack D, pivoted lever E, block or plunger k3, lever K,connecting-rod la, and latch L, substantially as shown and described.

In Witness whereof I have hereunto set my hand.VV
